Yes, me too.
Just google it "acne related to ejaculation" and you will see a lot of testimonies. Statistically, it must prove the link.
Now, lot of them don't have pois. I think acne is just a sign of hormonal fluctuation in body. Even if testosterone and hormones seems stable after ejaculation, there is an activity triggered by orgasm.
And this acitvity don't work very well for us.
I even found
forums where men are practicing abstinence, not for pois, but acne.
There is also this chinese study showing the link between ejaculation and abstince on a cycle of 7 days. Difficult to understand. But a part of the pois is here.
